Binary reproducible builds mean that if you and I start with the same 
source code and same build tools, we will get exactly the same build 
artifacts.  Here the build can't "depend on what date you use": you 
can't choose a date or another, the date is part of the code you are 
trying to build.  So if you and I build from the same commit, we'll 
build using the same date, whatever date is in the version.h file.
